Temperature control safety explosion-proof lamp

Abstract

The invention relates to a temperature control safety explosion-proof lamp. The temperature control safety explosion-proof lamp comprises a shell, a lamp piece and a lampshade. A good-heat-conduction heat dissipation block is attached to the back face of the lamp piece, annular cylindrical partition plates are mounted in the shell, and two cavity dividing plates are symmetrically mounted in a sealed annular cavity defined by the partition plates, the shell and the lamp piece; the annular cavity is divided into two independent semicircular liquid storage cavities through the cavity dividing plates, and horizontal semicircular piston pieces are mounted in the liquid storage cavities; the positions above the piston pieces are filled with a cooling agent, and the positions below the piston pieces are filled with air and expansion glue; and cooling holes communicated with the cooling agent are formed in the upper portions of the partition plates, and air inlet holes are formed in the lower portions of the partition plates. According to the explosion-proof lamp, the temperature inside a lamp body can be effectively reduced, safe and stable running of the explosion-proof lamp can be ensured, meanwhile, the explosion-proof lamp has the shutoff protection function, and the phenomenon that after the lamp body is exploded, electric sparks are still generated is effectively avoided.

Description

technical field [0001] The invention relates to an LED lighting fixture, in particular to an explosion-proof lamp. Background technique [0002] Explosion-proof lamps refer to lamps that take various specific measures to prevent the ignition of surrounding explosive mixtures such as explosive gas atmospheres, explosive dust atmospheres, gas gases, etc.; it is widely used in oil mining, oil refining, chemical industry, coal mines, railways, flood control, Dangerous environments such as military industry and offshore oil platforms, oil tankers and other places; common explosion-proof lamps are divided into explosion-proof lamps, increased safety lamps, composite lamps, etc. according to the structural type; there are two reasons for the ignition of flammable gas mixtures by electrical equipment: One is the sparks and arcs generated by electrical equipment, and the other is the heating on the surface of electrical equipment; placing equipment that is prone to arcing inside the ...

[0002] Explosion-proof lamps refer to lamps that take various specific measures to prevent the ignition of surrounding explosive mixtures such as explosive gas atmospheres, explosive dust atmospheres, gas gases, etc.; it is widely used in oil mining, oil refining, chemical industry, coal mines, railways, flood control, Dangerous environments such as military industry and offshore oil platforms, oil tankers and other places; common explosion-proof lamps are divided into explosion-proof lamps, increased safety lamps, composite lamps, etc. according to the structural type; there are two reasons for the ignition of flammable gas mixtures by electrical equipment: One is the sparks and arcs generated by electrical equipment, and the other is the heating on the surface of electrical equipment; placing equipment that is prone to arcing inside the explosion-proof shell can effectively prevent explosions, but traditional explosion-proof lamps still generate high heat during operation. When the temperature reaches a critical value, it will still cause an explosion, so the traditional explosion-proof lamp still has a large safety hazard during use; in addition, the fragments emitted by some explosion-proof lamps when they explode and shatter will hurt the surrounding staff, and there are Greater personal safety hazard
